Watches
When coating watches with precious metals, performance matters as much as appearance. Scratch resistance, lightness, and dimensional stability depend on precise, non-destructive analysis of alloy composition and coating thickness to ensure reliable quality.
Are you ready to discover how our solutions support you?
Solve it with Labspec!
When coating watches with precious metals, PVD or CVD coatings, it is not only aesthetics that play a decisive role, but also properties such as dimensional stability, lightness or scratch resistance. Labspec XRF and tactile instruments allow you to non-destructively analyze precious metal alloys or the thickness and composition of the thinnest coatings, thus ensuring the quality of your watches.
Scrap gold
Are you handling used or scrap gold? Ensuring authenticity and accurate composition is critical to prevent counterfeits and comply with industry standards. Reliable analysis is essential for jewelry, dental gold, coins, bars, and electronic scrap like PCBs, watches, or contacts.

Gold bullion bars, gold granules and precious metal alloys
Gold bullion is high-purity physical gold produced in the form of bars or coins, primarily for investment purposes. For further processing and manufacturing, gold bullion and other precious metal alloys are also available as granules. Ensuring purity and accurate composition is essential for both investors and manufacturers.

Gold and precious metals in soils, ores, and as nuggets
Analyzing soil and ore is a crucial step in mining exploration. Highly sought-after resources such as gold, silver, and other precious metals often occur only in trace amounts or within complex rock compositions, making them difficult to identify. Sometimes, naturally formed gold nuggets are found. In these rare cases, reliable testing of their authenticity and purity is essential for assessing their value and selling or processing them further.
